Answers
Answer:
51
Step-by-step explanation:
2*5=10
3*10=30
11*1=11
10+30+11
51
Answer:
She has $51
Step-by-step explanation:
You would do 10*3 = 30 since she has 3 tens. Then you would do 5*2 = 10 since she has 2 fives. And then you would do 11*1 = 11 since she has 11 ones. Then after you do that you would add all of them together so you would do 30+10+11 = $51

Answer:
A) x < 9
Step-by-step explanation:
Here we have an open circle. Open circles are used for greater than signs (>) and less than signs (<).
Since we have an open circle, we can eliminate option C and option D.
Now, we look at the number line.
The point is at 9, and the line from the point is going towards the left (where the smaller numbers are.)
9 is greater than every number is going toward.
**Let x represent every number is going toward.**
Therefore, x < 9.

Shamika bought 3 skirts that cost $25 each before the discount. What was her total after thediscount?
A. $45.00
B. $48.75
C. $52.50
D. $56.25
Answers
Answer:
The answer is C and please give me brainliet And a like!
Where the above parameters are given, Shamika's total after the discount is $56.25. (Option D)
How to compute the above resultAccording to the table, if the total purchases are less than $50, the discount is 25%.
Shamika bought 3 skirts at $25 each, so her total purchase amount is 3 * $25 = $75.
Since $75 is less than $50, she qualifies for a 25% discount.
To calculate the discount, we multiply the total purchase amount by the discount rate -
Discount = 25% of $75 = (25/100) * $75 = $18.75
To find her total after the discount, we subtract the discount from the total purchase amount -
Total after discount = Total purchase amount - Discount
Total after discount = $75 - $18.75 = $56.25
Therefore, Shamika's total after the discount is $56.25. (Option D)

r 2- 12r - 28 = 0[tex]r 2- 12r - 28 = 0[/tex]
Answers
Answer:
Step-by-step explanation:
r² - 12r - 28 = 0
r² - (14 - 2)r - 28 = 0
r² - 14r + 2r - 28 = 0
r ( r - 14 ) + 2 ( r - 14 ) = 0
( r - 14) ( r + 2 ) = 0
Either
r - 14 = 0
r = 14
or
r + 2 = 0
r = -2
therefore r = - 2 or 14

Answer:
its d..................
The sum of the expressions (-10x³ + 4x + 5) + (5x² - 2x) is -10x³ + 5x² + 2x + 5.
Thus, option (D) is correct.
In mathematics, an expression is a combination of numbers, variables, and operators (such as addition, subtraction, multiplication, division, and exponentiation) that represents a mathematical statement.
To find the sum of the given expressions (-10x³ + 4x + 5) and (5x² - 2x).
Simply combine like terms:
(-10x³ + 4x + 5) + (5x² - 2x)
Combining the like terms, we have:
-10x³ + 5x² + (4x - 2x) + 5
Simplifying further, we get:
-10x³ + 5x² + 2x + 5
Therefore, the sum is: [tex]-10x^3 + 5x^2 + 2x + 5[/tex].

For this I think you should know what SOH-CAH-TOA is, if not here.
O=opposite, A=adjacent(side), and H=-hypotenuse. We see they give us the right angle we need to solve, remember that we need the angle to the side of the right angle. Now S=sin, C=cos, T=tan, with these we use them to solve in the calculator. If you don't have a calculator, its going to be hard. But if you have a Ti-84 then set it to Degree mode. Ok moving on, We see they give us the adjacent and the hypotenuse, not the opposite.(from the given angle) So we can take off, SOH and TOA, see it doesn't have or has the incorrect sides. So we have left CAH.

the sun shines on a flagpole, causing a shadow to be cast on the ground. the distance from the base of the pole to the tip of the shadow is 49 feet. at that time of day, the sun's rays make an angle of 38° with the ground. How tall is the flagpole?
Answers
Answer:
30.17feet high
Step-by-step explanation:
Given the following
the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)
angle of elevation = 38°
Required
Height of the flagpole (opposite)
Using the SOH CAH TOA identity
Sin theta = opposite/hypotenuse
Sin 38 = H/49
H = 49sin38
H = 49(0.6157)
H = 30.17feet
Hence the flagpole is 30.17feet high

The distance between the pirate and the treasure can be found from the following relationship between ΔEAF and ΔABC;
[tex]\overline{AE}[/tex]/[tex]\overline{AB}[/tex] = [tex]\overline{FA}[/tex]/[tex]\overline{AC}[/tex] = [tex]\overline{EF}[/tex]/[tex]\overline{BC}[/tex]
Step-by-step explanation:
From the question diagram, we have two triangles, ΔEAF and ΔABC;
The ratio of the lengths of the sides [tex]\overline{AE}[/tex]/[tex]\overline{AB}[/tex] = [tex]\overline{FA}[/tex]/[tex]\overline{AC}[/tex]
∠EAF and ∠BAC are vertical angles, therefore ∠EAF = ∠BAC
Therefore, ΔEAF and ΔABC are similar triangles by Side-Angle-Side, SAS, rule of similarity which states that two triangles that have ratios of a pair of their corresponding sides and the two sides also form equal angles within each triangle, then the two triangles are similar
Therefore, the ratio of the each pair of corresponding sides of the two triangles are equal
We have;
[tex]\overline{AE}[/tex]/[tex]\overline{AB}[/tex] = [tex]\overline{FA}[/tex]/[tex]\overline{AC}[/tex] = 50 ft. /(100 ft.) = [tex]\overline{EF}[/tex]/[tex]\overline{BC}[/tex] = [tex]\overline{EF}[/tex]/120 ft.
[tex]\overline{EF}[/tex] = 120 ft. × 50 ft./(100 ft.) = 60 ft.
[tex]\overline{EF}[/tex] = 60 ft.
The distance between the pirate and the treasure, [tex]\overline{EF}[/tex] = 60 ft.

Step-by-step explanation:

450-380 = 70
70/35=2
Answer:
Each performer can get 2 guests.
Step-by-step explanation:
There are 35 performers and 345 pre-sold tickets, so we just need to subract them from the amount of people that the stadium can hold. 450 - 35 - 345 = 70 people left
Since there is space for 70 more people, each performer can get (70/35) = 2 guests
